This invention relates'- in general to akitchen sinl: and sink assembly,and more particularly to an assembly of this character wherein aneffective and permanent seal is provided between the drain boardcovering andthe sink.

lin kitchen sink assemblies. the d-rain boards are constructed of a hardrigid material or a relatively resilient material. The former includesthose made of til'e, cement, metal and those which are formed as part ofthe sink itself. The latter includes those made of wood and thosecoveredi with linoleurn or a similar covering.

Hard surfaced drain boards have been foundl unsatisfactory since such asurfacel results in excessive breakage' of china and glassware.- Tileandl cement drainl boards' arefbrittle' and easily chipped in normal'usage.

Woodenn drain beards are unsatisfactory since they warp, crack' andiabsorb moisture, thusI becoming sour and impossible to clean properly.Although linoleufin-ocu/eredZ drain boards are" de-V sirable in thatthe: breakage of chinaand glassware is minimized, likek those o'i ahardsurface and those constructed of wood; they are unsatisfactory inthat ithas been"A impossible, heretofore, to eiect` a permanent water-tightseal between the drain boardand' the sink. This results in liquids and'the particles of' fe'odi carried by these liquids seep'ing' between-#thesink and drain boa-rd where they' cannot'beremoved Normally kitchensinks are constructed with anv outwardly extending peripheral ange whichis generally usedr to suspend the sinks of their. cabinets orfrai'ne'works.4 In manu-factura the entire working, surface ofA thesesinks, including the flange, is enamel-coated. When'the enamel isapplied to the sinks', they are subjected to such high temperaturesVthat the: anges are warped and', as a result, their surfaces are rippledand uneven. Av permanent wateretight seal must be effected between thisuneven surface" of the' iian'g'e and the drain board. if. the assemblyis to be maintained in a sanitary condition. However, such a seal hasnot been devised since cement seals willl not properly adhere'. to theenameled surfaces, and metal. trim seals cannot be molded or bent so asto` snuglyfit the irregularities-.of the uneven surface of the aiige;

It is thel object of this; invention to provide a generally improvedkitchen sinkV and drain board assembly wherein` a: permanent water-tightseal is effected between a:- resilient drain board Cov-'i ering andasinkhaving anevenand true upper edge.

I-t is iur-ther am obie'ctl- 0f; this invention to` pros vide a kitchensink assembly comprising. a drain board; a sink rigidly afiixedl to saiddrain wboard with theupper` edge of itsI peripheral wa'll flush withandext'ension of" the upper surface of said drain board; a tri-ni seallf-'shaped in cross-sec'- ticnsnuglyaffixed to said'- drain board' andlsink withz its leg nre-'rubenoverlyingY the joint between the sin-k anddrain board andi the lower portion of its c'r'o's's member overlappingthe upper margin of said peripheral wall; anda drain board coveringcemented over-trie ieg of said trim sea1 and over thedrain board withits'- edge' abutting the upper portion' oftllet'riin sea-l;

While theinnel'fsulffaidotl silfy l ny'bedf'ed'lwlthl porcelaiuan upperi'edg'-"its peripheral-wall is uncoate'd andi.oanfbefnaeh-inedlso? as to havey atrue and ever surface. The drain'f board iii is formed with a cut-outsection, the periphery of which conforms tothe outer surface-of thewall'S.

Integrallyvformed with the outerL surface of eachr of the end. sections:ot the? peripheral'v wall 5 are formed-i with.- a plurality of'longitudinally aligned, threaded holes 6ta-'spaced distance apart, each*of: which suitably threaded-.to receive a bolt la Aixed .to rthe lbwe'nsurface: ofi!- the 'drain beardI 2` immediately adda-cent tov-and:parallel withleach of.. th'evfangesf'effis aniangl'efiro t; Theproject'- ingi ear ofthe-anglefironis is.; ined; with aiplu'- rality'.of'. laterally vdisposed/1.slots? 9,- one being'- iny 3 register witheach of the threaded holes 6 in the ilanges 5.

In mounting the sink I on the drain board 2, the former is positionedwithin the cut-out section in the latter so that the upper edge ofperipheral wall 3 of the sink I is ush with the upper surface of thedrain board 2. The sink I is then rigidly secured to the drain board byengaging the slots 9 in the angle iron 8 with the bolts and tighteningthe same. As illustrated in 2, the slots provided in the angle iron 8permit the sink to be adjusted during installation in relation to thedrain board 2 a suiicent amount so that the upper edge of the peripheralwall 3 can be positioned iiush with the upper surface of the drain board2. When the bolts 'I are tightened, the sink is rigidly secured to thedrain board. This rigid connection is of sufficient strength to maintainat all times the relationship of the sink to the drain board 2 so thatthe seal is never broken by movement of the sink or the drain board 2.

Mounted on the upper surface of the drain board 2 with its lower portioni'l overlapping an upper margin of peripheral wall 3 is a metal trimseal I I, T-shaped in cross-section. As illustrated in Fig. 1, the legI2 of the trim seal II extends outwardly from the sink a sufficientdistance to permit its attachment to the drain board E by means o1"screws I3. the trim seal Il is undercut to receive a drain boardcovering I5 which is cemented or othern Wise fixed in position on top ofthe leg of the trim seal II. In order to eliminate any bulging orunevenness in the covering I5, a strip of material I6 of a thicknessequal to that of the leg of trim seal II is positioned in abutment withthe outer end of the leg I2 of the seal II extending intermediate thedrain board 2 and the covering I5.

it should be noticed that the leg I2 and the upper portion I4 of theseal II form an undercut angle in which the edge of the covering IE canbe securely positioned so as to effect a watertight joint. It should be`further noticed that the line of contact between the sink I and thedrain board 2 is completely covered by the trim seal II and the coveringI5. As is customary, all contacting parts of the trim seal I I arecoated with a cementing compound IB to insure watertight joints.

From the foregoing description, it is apparent that a permanentWater-tight seal has been eiected between the drain board covering andthe upper edge of the sink. If any liquid is to seep between the sinkand the drain board covering, it must first travel upwardly between thelower portion II of the trim seal and the sink and then travel betweenthe leg I2 of the trim seal and the abutting even upper edge of thesink.
